The Sharks began overtime on a 5-on-3 power play after Robyn Regehr went off for hooking Tommy Wingels and 19:18 of the third and Trevor Lewis went off for goalie interference for running into Antti Niemi with five seconds left.

After the first power play ended, Couture set up in the slot and received a one-touch pass from Patrick Marleau, burying the puck high past Jonathan Quick for the win and his fourth of the playoffs.

Couture missed about 15 minutes in the second period after a hit by Carter sent him flying into the boards awkwardly. He held his leg as he left the ice. This was after the Sharks lost Scott Hannan and Marty Havlat to injury in the game.

Dan Boyle gave the Sharks the lead early in the power play after Jake Muzzin shot the puck over the glass at 1:30 of the first. Tyler Toffoli of the Kings tied the game at 10:08 after a Sharks turnover.
